But it looks like the old usb code didn't call it either... I think
old code enumerated right away during boot, while the new code defers
the enumeration until events can be processed...
Yes, you're right. USB1 used the following:
SYSINIT(usb_cold_explore, SI_SUB_CONFIGURE, SI_ORDER_MIDDLE,
usb_cold_explore, NULL);
SI_SUB_CONFIGURE didn't complete before all USB busses
were enumerated.
